Honeywell PCR-110 - Manual (Page 10)

7.1 Input parameters and input ranges:
Parameter on display Setting range
( or ) ( and or ) Preset
E00 Cold store temperature difference 1 to 20 K 2 K
E01 Min. permissible
cold store temp. –55 °C to E02 –55 °C
E02 Max. permissible
cold store temp. E01 to +50 °C +50 °C
E03 Delay time,
relay energizing 0 to 15 mins. 5 mins.
E04 Alarm temperature difference –50 K to +50 K 20 K
If the set temperature difference E04 is negative, an alarm is given
if it is too cold in the refrigerated area,
e.g. E04 = –10 K, cold store setpoint value = 18°C
➝ alarm at –28 °C in refrigerated area.
If the set temperature difference E04 is positive, the alarm is given
if it is too warm in the refrigerated area,
e.g. E04 = +10 K, cold store setpoint value = –18°C
➝ alarm at –8°C in refrigerated area.
Attention: any change of coldstore set point value changes also the
alarm temperature.
If E04 is set to 0, no alarm will be given.
E05 Alarm delay time 0 to 99 mins. 10 mins.
E06 Sensor calibration T1 –5 to +5 K 0 K
E07 Mode selection 1 = Cooling, 1
2 = Heating
E08 Time between 2 defrost cycles 1 to 24 hours 8 hours
(switch off cooling)
☛ Once the controller has been switched on, defrosting occurs
for the first time at the end of the first time interval.
☛ After defrosting has been initiated manually, the next time
defrosting takes place is after a complete time interval has
elapsed.
